Mafia Island

Tanzania’s Quiet Island Escape

Much of the island’s appeal comes from its unhurried atmosphere and marine life, making it ideal for travellers who want diving, snorkelling and nature without the busier resort feel.

Why Visit Mafia Island?

Exceptional Marine Life

The waters around Mafia are among Tanzania’s most rewarding for snorkelling and diving, with coral reefs, tropical fish and a rich marine ecosystem.

Whale Shark Season

Mafia is especially famous for seasonal whale shark encounters, offering the chance to experience one of the ocean’s most extraordinary animals.

Quieter Than Zanzibar

The island feels much more low-key, with fewer large resorts and a stronger sense of local island life.

Perfect After a Southern Safari

Its location makes Mafia especially attractive after Nyerere, Mikumi or other southern Tanzania experiences.
